CONVEYEB SYSTEM.

Application filed October 11'), 1821.

To (ZZZ whom it may concern Be it lrnown that T. has W. Brown. a citizen of the United in es. residing r m 1 ,1. OiHCEl/QO, in the cor ntv or L/Oik and 7 0 a 0 or illinois, have t a certain new and useful Improven" a part of this specification.

My invention relates to conveyor systems and is concerned more particularly with conveyer systems for ejecting or discharging ashes ships and the like.

Systems or this type having discharge openings on one side of the ship only are obiectionable. For example. where the sea is running heavy or the water is for any other reason higher on the side on which. the openings are arranged or where th ship lies with such side toward another ship or toward the wall of a whari it is either impossible to discharge or eject the ashes or the adjacent ship or wharf is spattered by such discharge.

Attempts have been made to overcome these diiliculties by arranging a single vertical supply or ascension pipe between the opposite sides of the ship and leading a pair of discharge pipes out through the sides of the ship from the upper end of this vertical pipe. Furthermore. the arrangement structural details of such a system are objectionable and complicated provisions are necessary tor directing the discharge through the desired discharge pipe. I My present inven ion aims to provide a novel, simple and improved conveying systern for discharging the ashes from either side of the ship at will. The system which I have devised to these ends embodies not only an improved arrangement and improved structural details, but functions in an improved manner. There is no division box nor the complicated mechanism associated therewith for directing the discharge through the desired discharge pipe and the difioulties encountered upon failure of such arrangement are thereby avoided. The extreme simplicity and advantageous arrangement of the piping or conduit system employed is a highly important aspect of my invention.

According to my invention, a common ash receiving conduit arranged horizontally beneath the boilers of the ship is adapted Serial No. 506,870.

to have as many ash receiving or admission openings as may be desired for the particular boiler system in question. This common horizontal conduit communicates with a pair of vertical discharge pipes. one eX- tcnding up alone each of the opposite Sides of the ship and discharging through the adjacent side of the hull of the ship as high above the water level as conditions will permit. Suitable ejectors are provided for discharging the ashes from the common hori zontal conduit out through either of the vertical discharge pipes and out through the desired side oi the ship.

Other aims of my invention not already set forth will appear from the following cletailed description and the claims taken with inspection of the accompanying draw ings, in which I have disclosed a particular embodiment of my invention in order to explain more fully to those skilled in the art how to construct and practice the same:

In the drawings:

Figure l is a diagrammatic cross sectional view of a ship showing an embodiment of my invention;

Figure 2 is a diagrammatic plan view of the same;

Figures 3 and d are reduced diagrammatic cross sectional views of a ship illustrating one of the advantages of my invention;

Figure 5 is an enlarged vertical sectional view through one of the ejector elements employed; and

Figure 6 is a perspective view of one oi the ash intake covers.

With reference now to the particular embodiment of my invention selected for illustration, 5 denotes the ash receiving conduit arranged athwartship beneath the boilers 6. The conduit 5 is preferably made up of a plurality of sections joined together as by means of suitable flanges 7 and supported in suitable cradles 8.

The conduit is provided with as many ash receiving or admission openings 9 as may be desired for the particular boiler system 6 employed. These ash receiving or admission openings 9 are provided with suitable hoppers 11 bolted or otherwise socured in place. The hoppers 11 terminate at their upper ends in plate like portions which abut the under surface of the boiler room floor 12 beneath the openings 13 provided therethrough. The openings 13 are arranged to receive the ashes from the into the conduit 5.

ash discharge hoppers of the boiler system. The conduit 5 is provided with clean-out openings 14 adjacent each of its opposite ends and an intermediate clean-out opening 15. The ash intake and cleanput openings along the conduits 5 are provided with covers 16 (Figure 6) for preventin the entrance of water from the boiler room floor Covers 16 have imperiorate bottom walls and their upper surfaces are recessed to form handles and permit access to said handles.

Air is admitted to the system through either of a pair of inlets or vents as or 45 arranged adjacent the opposite ends respectively of the conduit 5. The upright funnels through which the air inlets or vents 45 and 4-5 are supplied are bolted or otherwise secured in place and provided with water tight covers46.

Ejectors 17 and 17' preferably although not necessarily of the type shown in detail in Figure 5 are connected to the opposite ends respectively of the conduit 5.- he ejector shown comprises a body portion or fitting 18 having an inlet opening 19 and a discharge opening 20. A plug 21 in the opening 22 of the fitting 18 provides an abutment facing the direction of motion or. conveyed material therethrough. A nozzle 23 for directing a jet of steam or such other propulsion means as is employed is supplied from any suitable source as by way of a pipe line 24:. The pipe lines 2-; are provided with suitable valves 25 and drain cocks 26.

A vertical discharge pipe 32 connected at its lower end with the discharge opening 20 of the fitting 18 at one endof the conduit 5, extends up along the side 27 of the hull 28 and opens therethrough by way of a T-connec'tion 29, relatively short pipe 30 and outlet 31. A imilar discharge pipe 33 is connected at its lower end with the discharge opening 20 of the T fitting, at the opposite end of the conduit 5, extends up along and opens through the side 3 oi the hull by way of a T connection 35, relatively short pipe 36 and outlet 37.

The outlets 31 and 37 open through the respective sides oi the hull as high above the water level as conditions will permit. These outlets are provided with suitable closure members 38. These closure members may be in the form of plates or gates pivoted as shown to be swung into open or closed position as desired, or they may be slidable into open or closed position or of anyother desired form.

The T connections 29 and 35 are substantially identical with the T connections 18. While a water spray is not ordinarily necessary in the system of my invention, should such a spray under certain conditions be found desirable, suitable water lines 39 are connected into the T fittings 29- and 35 as shown. An admirable mixing chamber is thereby provided for thoroughly wetting the ash dust, with minimum quantity or water. if the water spray is not desired, the plug 10 (Figure 5) which plug provides for connecting either a steam or water line to the T, is rei'nove'd, and an imperforate plug is inserted in its stead. The water lines 39 are provided with suitable valves 41.

The operation of the system described is follows:

When it is desired to eject the ashes through the discharge opening 37 as for example, upon settling of the ship upon its side 27 as shown in Figure 3, the gates 38 normally closing the opening 37 are moved into open position, the cover 46 is removed from the funnel through which the air inlet 15 is supplied, and a flow of steam or such other propulsion fluid as is employed, is set up through the ejector 1 8. The ashes which are periodically discharged from the boiler 10 into the conduit 5 through the openings 9, are thereupon conveyed with the air drawn in through the inlet 15. Movement at high velocity is expedited by the steam jet discharging through the ejectOr 18' up through the vertical discharge pipe 33, T 35, relatively short pipe 36 and out through the outlets 37'.

When it is desired to eject the ashes through the openings 31, the gates or closure plates 38 are moved into open position. This time the cover 46 is locked in place on the funnel'through which the air inlet a5 is supplied, and the cover removed from the funnel through which the air inlet 45' is supplied. A flow of steam is then set up through the ejector 18 conveying the ashes up through the discharge pipe 32, T 29, relatively short pipe 30 and out through the outlets 31.

In the system of my invention the thorough mixture of the ashes and steam practically eliminates the dust nuisance. However, where a water spray is desired, a flow is set up by way of either of the water-lines 39 through the particular T 29 or 35 through which the ashes are being conveyed thoroughly wetting any ash dust with a minimum quantity of Water.

While the various details shown are now considered preferable, it is to be understood that such details as well as the particular manner of setting the several elements to se cure the desired discharge may be varied within the spirit and scope of my invention.

1. In combination, a pair of vertical discharge pipes, a common horizontal supply pipe communicating with said discharge pipes, said common horizontal supply pipe having a pair of air intakes and a plurality of admission. openings therebetween, and

means for creating a current of air through the common supply pipe and either one of the discharge pipes.

2. In combination, a pair of vertical discharge pipes, a common horizontal supply pipe, coupling members between the opposite ends of said common horizontal supply pipe and said vertical discharge pipes and means for introducing a propulsion fiuid through either of the coupling members at will to create a fluid flow through the common supply pipe and one of the discharge pipes.

3. In combination, a pair or" vertical discharge pipes adapted for opening through the opposite sides of a ship, a common horizontal supply pipe, coupling elements between the op osite ends of the common horizontal Suppl; pipe and said vertical discharge pipes, means for introducing a propulsion fluid through either of the coupling members at will to create a fluid flow through the common supply pipe and one of the discharge pipes, coupling elements between the vertical discharge pipes and the outlets through the sides of the ship, and means for introducing a liquid spray through said coupling elements.

In witness whereof, I hereunto subscribe my name this 6 day of September, 1921.
